To keep the first group open to prevent it from collapsing in the GroupCollapsed event, use the following code:
Protected Sub C1WebTopicBar1_GroupCollapsing(ByVal sender As Object, ByVal e As C1.Web.Command.C1WebGroupBeforeEventArgs) Handles
C1WebTopicBar1.GroupCollapsing
If e.Group.Index = 0 Then
e.Cancel = True
End If
End Sub
• C#
protected void C1WebTopicBar1_GroupCollapsing(object sender, C1.Web.Command.C1WebGroupBeforeEventArgs e)
{
if (e.Group.Index == 0)
{
e.Cancel = true;
}
}
